HINRICH B. SCHUTT, OF BROOKLYN, NEW YORK.-

STRUCTURAL lmTAL-WORK IN BUILDINGS.

No. 89e,815.

Specification of Letters Patent.

Patented July 21, 1'908.

Application led February 18, 1907. Serial N o. 357,834.

T o all whom it may concern:

Beit known that I, HINRIcH B. Scrm'i'r, a citizen of the United States,and resident of Brooklyn, county of Kings, and State of New York, haveinvented certain new and useful Improvements in Structural Metal-l Workin Buildings, of which the following is a specification, reference beinghad to the accompanying drawing, forming a part thereof, in whichsimilar lettersof reference indicate corresponding parts.

, This invention relates to structural metalwork of the characteremployed in constructing steel or iron-frame buildings; the objectsthereof being to provide parts to be employed in structures of thischaracter which are of such novel formation as to be interlocked andassembled without the necessity of using either rivets or bolts andnuts, whereby the process of constructing an iron or steel-framebuilding comprising a plurality of such parts is greatly facilitated andthe cost of the structure is considerably lessened.

The invention will be hereinafter fully described and specifically setforth in the annexed claims.

In .the accompanying drawings forming part of the specification, Figure1, is a perspective view of a lateral beam forming part of my invention;Fig. 2, an end elevation of a part of a cross-beam having one of thesaid lateral beams coupled thereto; Fig. 3, a vertical sectionalelevation taken on the line 3 3, of Fig. 2; Fig. 4, a sectional planviewtaken on the line 4-4, of Fig. 3; Fig. 5, a

similar view showing a double-coupling; Fig. 6, a side elevation, shownpartly in section, illustrating the application of my invention as -a'means for coupling horizontal beams'to 'a vertical column; Fig. 7, aperpective view of the en d of a horizontal beam;

g. 8, a sectional planview showing three horizontal beams in positionpartially connected, and Fig. 9, is a perspective view of part of avertical column.

In the examples of my invention shown by` the drawings A,illustrates-the lateral beams and IB, the main or cross-beams. The beamsA, are provided at each end with a tongue 1;

the said tongues being extended at right angles from .and formedintegral with the stem a, of the beam A, the flanges of said beams beingcut away as shown. The said tongues are extended in opposite directionsand approximately at right angles from' the said stem a, and they may beof any desir- Aable proportion, each being provided on its Y under sideand near the point of intersection with the stem a, with a notch 2, forengagement with a part of the stem of an adjacent beam, as will behereinafter described.

The beams B, are provided with horizontal pockets 3, formed integralwith their stems b, and vertical slits 4, adjacent thereto. Where twolateral beams A, are to be connected to a main beam B, as shown by Fig.5, of the drawings, double pockets 5, are provided, having a slit 6,located between them, the same being formed integral with the stem b,one on each side' thereof. zontal beam, as C, Figs. 6 and 7, is to beconnected to a vertical column or post, as D, the latter is providedwith vertical pockets 7, and adjacent slits 8; and the horizontal beams,as C, are provided with downwardly gral withand extend approximate-l yat right angles from' the flanges l0; the stems c, be-

stems are sufliciently deep to snugly accommodate the tongues l, wherebythey register with said stems; and they are sulficiently high to allowthe said tongues to freely enter during the operation of assembling thearts. P In assembling a structure, two cross-beams B, being placed withtheir pockets 3, opposite to each other, a beam A, is swung between themas shown in Fig. '8, of the drawings, then the same is forced intoposition at right angles relative to the beams B, as shown by Fig. 4, ofthe drawings, with the pockets and tongues in snug engagement.Afterwards 4the beam A, is driven downwardly until 1pts notches 2,engage the stemparts of the beam B, immediately beneath them, wherebythe main and lateral beams are securely locked together, and gravityholds the beam A, 1 11 place and liability of lateral displacement 1sobviated; thus secure assembl of beams at right angles to each other seffected W1th outl the aid of'straps, brackets, rivetstor nuts andbolts. The horizontal end beams of a structure are also readilyconnected to their adjacent uprights Without the aid of supplementarymeans for fastening as shown by a assembled.

I do not conne myself to specific forms of When a horiing'cut away asshown. The pockets of theV Fig. 6,of the drawings. By this mode ofIconstruction a whole metallic frame Work of. may be quickly andeconomicallyv extended tongues 9, which arc formed intethe parts nordetails of construction. as here- Y ters Patent, is

1. In structural metal-work, the combination with a part having pocketsand slits adjacent to said pockets and leading into the said pockets atright angles therewith, and

beams having notched end tongues extending at' right angles thereto, thesaid tongues engaging the said pockets and when in such engagementextending parallel therewith, substantially as shown and described.

2. In structural metal-work for bildings, the combination with beamshaving horizontal pockets in their stems and vertical slits adjacent tosaid pockets, of beams at right angles therewith and having tonguesengaging said pockets and extended parallel therewith, substantially asshown and described.

3. In structural metal-work for buildings, the combination with beamshaving pockets in their stems and slits adjacent to said pockets,- ofbeams having4 tongues engaging said pockets, the said tongues ravingnotches engaging over parts of the stems, substantially as shown anddescribed.

4. As a new article of manufacture to be employed as a part of ametallic frame-work of a building, a metallic beam having end tongues ateach end thereof, extending in opposite directions Iat right anglesthereto, and by reason of their construction and arrangement aifordingfacility for engaging pockets in the beams next adjacent thereto,substantially as shown and described.

5. As a new article of manufacture to be vemployed as a part of ametallic {raum-work of a building, a metallic beam having end tongues ateach end thereof, extending in opposite directions and at right anglesthereto, said tongues having each a notch therein, substantially asshown and described.

1n testimony that I claim the foregoing as my invention, I have signedmy name in presence of two witnesses, this 11th day of February 1907.
